Steel and iron. Determination of phosphorus content. Phosphovanadomolybdate spectrophotometric method1 Scope This International Standard specifies a spectrophotometric method for the determination of phosphorus in steel and iron with the following limitations. The method is applicable to phosphorus contents between 0,001 0 % (m m) and 1,0 % (m m). Arsenic, hafnium, niobium, tantalum, titanium, and tungsten interfere in determining phosphorus, but the interferences tan be partially overcome by formation of complexes and use of small quantities of test
